Letters Patent No. 87 ,681, dated March 9,' 1869. i

IZMPROVENIENT IN CARBUBE'TTI-NG- AND IN OIL FORTES SAME.

The Schedule referred to in these Letters Patent and mak-ling part of the same. l

i flcation.

My invention is an improvement upon two former inventions for carburettiug gas by the heated vapor ot heavy 011s, for which Letters Patent were.A granted to me, the first, No. 62,855, dated'Mareh 12, 1867, and` the second, No. 83,289, dated October 20, 1868.V Those inventions show methods of lvaporizmg the oil by the heat'of the combined gasand vapor ame, from the top or sides of its vertical column,vso that the heat to the carburetting-vessel is not checked by 'the deposit' of tarry matter at the bottom .of the vessel.

My present improvements consist inthe methodof heating the carburetting vessel, and iu preparing .the carburetting-oil to be used in the apparatus, so as to remove the tar therefrom.

1n the preparation of the oil, I rst heat the still or retort containing coal or otber'oil, to about 420 Fahrenheit scale, and allow all oil that will evaporate at .or near this temperature, to pass olf or distilover, after which I raise the temperature 'of the oil in thestill to aboutl 52()o Fahrenheit scale, and condense and collect all the oil that-passes over up to this temperature, and use it mixed with as much naphthaline as it will hold in soluf tion, for the purposes 4f my invention.

The oil thus prepared will be found nearly free from tarry matter, and maythen beevaporated and mixed with gas in a carburetting-vessel, heated fromthe'bottom or top ofits vertical column, or in any other con: venient way, by the4 heat of the gas-flame placed either above or under the vessel.

My improvements show the gas-flame placed at a distance from the carburetter.

The 'heat is conducted by a suitable pipe to vaporize he oil placed in the garburetting-vessel, taking care a1- ways to keep the gas-pipe leading from the vaporizingvessel to the burner, at high temperature, to prevent condensation ofthe heavy vapors passing with the gas through the pipe. This I accomplish by enclosing the outlet-gas pipe in the hot-air tube.

Description of Drawing.

Figure 1 is avertical section 'of an apparatus, showing my improvements, with hot air'tube attached, suitable for lighting large halls.

Figure 2 is a modification of the same.

A shows the carburetting-vessel.

Bis the inlet,and

G, the outlet-pipe.

D, the oil-feed pipe, for supplying the carburetter with oil.

E is lthe heat-intercepter, or damper, made to open or close the hot-airchannel, so as to regulate the heat to the carburetter.

Gr G Gr show hot-air channel.

F, the burner, and

H, the reflector.

This apparatus is intended to light large halls.

The burner andvreector are made to lit into or project below the hall-ceiling, and the carburetting-vessel is intended to be placed above the ceiling. The damper E is moved from any partof the buildings by a wi-re or.

bell-hanging arrangement attached Ato lever I.

Fig. 2 shows modification of fig, 1', with the carburetter placed in the hotfair channel, and made oblong.

The feed-piped), in this modification, may be carried and the oil supplied from outside the building.

1H shows the reiiector, made convex.

-I claim, as new-i The general arrangement and method of heating the carburetting-vessel, together 'with the mode. of preparing the oil, as described, fory carburetting` gas.

The above specification of ,my invention signed by me, this 28th day of November, 1868.
